At below of the struture, there is a ground plane (in orange). After you have a dieletric FR4 with inside a copper strip line and a copper connetor. I have an input at the end of the strip lne in red and an output at the end of the connector. My problem is how to define the port 1? The port 2 can be realized with a wave port between the top of the strip line and the ground.
Thank you for your response.
